# --description--

The `range()` function returns an immutable sequence of numbers. As you can see, the data type of `rods['A']` is `range`, but you want it to be a list.

Pass your `range()` call to the `list()` function to do that.

# --hints--

You should pass your `range()` call to the `list()` function.

```js
({ test: () => assert(__pyodide.runPython(`
  a = __locals.get('rods')
  a['A'] == list(range(3, 0, -1))
  `))
})
```

# --seed--

## --seed-contents--

```py
--fcc-editable-region--
rods = {
    'A': range(3, 0, -1),
    'B': [],
    'C': []
}
print(type(rods['A']))
--fcc-editable-region--
```
